High Quality Content by WIKIPEDIA articles! A virtual retinal display (VRD), also known as a retinal scan display (RSD) or retinal projector (RP), is a display technology that draws a raster display (like a television) directly onto the retina of the eye. The user sees what appears to be a conventional display floating in space in front of them. (However, the portion of the visual area where imagery appears must still intersect with optical elements of the display system. It is not possible to display an image over a solid angle from a point source unless the projection system can bypass the lenses within the eye.)

The Virtual World Framework (VWF) is a means to connect robust 3D, immersive, entities with other entities, virtual worlds, content and users via web browsers. It provides the ability for client-server programs to be delivered in a lightweight manner via web browsers, and provides synchronization for multiple users to interact with common objects and environments. For example, using VWF, a developer can take video lesson plans, component objects and avatars and successfully insert them into an existing virtual or created landscape (such as EDGE or Open Sim), interacting with the native objects and users via a VWF interface.

A virtual team (also known as a geographically dispersed team or distributed team) is a group of individuals who work across time, space and organizational boundaries with links strengthened by webs of communication technology. Powell, Piccoli and Ives define virtual teams in their literature review article "as groups of geographically, organizationally and/or time dispersed workers brought together by information and telecommunication technologies to accomplish one or more organizational tasks." Ale Ebrahim, N., Ahmed, S. & Taha, Z. in their recent (2009) literature review paper, added two key issues to definition of a virtual team “as small temporary groups of geographically,...

Virtuoso Universal Server is a middleware and database engine hybrid that combines the functionality of a traditional RDBMS, ORDBMS, virtual database, RDF, XML, free-text, web application server and file server functionality in a single system. Rather than have dedicated servers for each of the aforementioned functionality realms, Virtuoso is a "universal server"; it enables a single multithreaded server process that implements multiple protocols. The open source edition of Virtuoso Universal Server is also known as OpenLink Virtuoso. The software has been developed by OpenLink Software with Kingsley Uyi Idehen and Orri Erling as the chief software architects.

High Quality Content by WIKIPEDIA articles! A visbreaker is a processing unit in oil refinery whose purpose is to reduce the quantity of residual oil produced in the distillation of crude oil and to increase the yield of more valuable middle distillates (heating oil and diesel) by the refinery. A visbreaker thermally cracks large hydrocarbon molecules in the oil by heating in a furnace to reduce its viscosity and to produce small quantities of light hydrocarbons (LPG and gasoline). The process name of "visbreaker" refers to the fact that the process reduces (i.e., breaks) the viscosity of the residual oil. The process is non-catalytic.

High Quality Content by WIKIPEDIA articles! Viscosity is a measure of the resistance of a fluid which is being deformed by either shear stress or tensile stress. In everyday terms (and for fluids only), viscosity is "thickness" or "internal friction". Thus, water is "thin", having a lower viscosity, while honey is "thick", having a higher viscosity. Put simply, the less viscous the fluid is, the greater its ease of movement (fluidity).

High Quality Content by WIKIPEDIA articles! In mathematics, the viscosity solution concept was introduced in the early 1980s by Pierre-Louis Lions and Michael Crandall as a generalization of the classical concept of what is meant by a `solution` to a partial differential equation (PDE). It has been found that the viscosity solution is the natural solution concept to use in many applications of PDE`s, including for example first order equations arising in optimal control (the Hamilton-Jacobi equation), differential games (the Isaacs equation) or front evolution problems, as well as second-order equations such as the ones arising in stochastic optimal control or stochastic differential games.
